Minor Description
Inspected daffodil 3.2.0 zip. Libs have log4j-api-2.13.2 and log4j-core-2.14.1. Checked why they aren't the same version. Checked how we add these libs,
project/Dependencies.scala 33: "org.apache.logging.log4j" %% "log4j-api-scala" % "12.0", 34: "org.apache.logging.log4j" % "log4j-core" % "2.14.1" % "it,test", 48: "org.apache.logging.log4j" % "log4j-core" % "2.14.1",
We specify version for jars in project/Dependencies.scala. Adding log4j-api-scala 12.0 also adds log4j-api 2.13.2 2.13.2 transitively but log4j-core 2.13.2 is a runtime dependency, meaning it isn't added transitively.
We added all these three lines to project/Dependencies.scala in PR #605 but we didn't add log4j-api for some reason even though log4j-scala's README suggests adding both log4j-api and log4j-core to our dependencies. We should add the same version of log4j-api for consistency, which will allow Scala Steward to bump both of them to even later versions (note log4j-api-scala 12.0 bases its API on log4j-api 2.13.2, but there should be no backward API incompatibilities in future log4j 2.x releases).
